Chemoselective flow hydrogenation of 6-methyl-5-hepten-2-one was performed over nano-nickel catalysts. The parent catalyst composed solely of nickel nanoparticles grafted on the polymeric resin exhibited high activity and selectivity towards CC bond saturation but its modification with small quantities of tin significantly increased its ability to perform CO bond hydrogenation. The post-synthetic modification of the parent catalyst was achieved by surface organometallic chemistry approach and performed in the same flow micro-reactor, which was used for the catalytic studies, providing a methodology for online modification of parent catalysts.

通过表面有机金属化学改性，在锡6-甲基-5-庚-2-酮的流动氢化中用锡调节纳米镍的选择性

在纳米镍催化剂上进行了6-甲基-5-庚-2-酮的化学选择性流动氢化。仅由接枝到聚合物树脂上的镍纳米粒子组成的母体催化剂显示出高活性和对C C键饱和的选择性，但用少量锡进行改性可显着提高其进行C O键加氢的能力。母体催化剂的合成后改性是通过表面有机金属化学方法实现的，并在用于催化研究的同一流动微反应器中进行，为母体催化剂的在线改性提供了一种方法。
